Depending on your version of Windows, Control Panel is usually available from the Start Menu or the Apps screen.

What you do next depends on what Windows operating system you're using:

In Windows 10 and Windows 8, tap or click on the Hardware and Sound link.

In Windows 7, click System and Security.

In Windows Vista, choose System and Maintenance.

In Windows XP, click Performance and Maintenance.

Note: If you don't see these options, your Control Panel view may be set to Large icons, Small icons, or Classic View, depending on your version of Windows. If so, find and choose Device Manager from the big collection of icons you see and then skip to Step 3 below.

2. Open Device Manager

In Windows 10 and Windows 8, check under the Devices and Printers heading.

In Windows 7, look under System.

In Windows Vista, you'll find Device Manager towards the bottom of the window.

From the open Control Panel window, click System, choose the Hardware tab, and then click the Device Manager button.
